Makes sense.

Anywhere but the BIOS attributes store on D-Bus? For eg could you come 
up with another D-Bus interface to house this property? The PLDM demon 
can relay a PLDM sensor to a D-Bus object that implements this property. 
There are other PLDM sensors that the host owns, that are already 
handled this way today - the host updates a PLDM sensor and lets the BMC 
know about it. The BMC can update a corresponding D-Bus property.
